Shepherds chapel is on analog C-band, I don't know if they have a digital version of that or not. What settings are you using for ku-band satellites, like G25 ku?? Didnt say what lnb you have, but for ku band satellites, you have to specify a "LO" or local oscillator freq for each satellite you scan, as in 10750 for the standard type ku lnbf, or 10600 for universal. For c-band sats, its 5150.(assuming you have a big dish to use also).
ALso I dl the manual for your rec, and it does claim to do blind scan, even though the ads I saw for it never mention it. Tell us what lnbf you have and maybe we can help you further, you should get around 200channels on G25 if your dish is aimed right.
